Technical Datasheet | Supplied by Evonik
VPS SIVO 280 by Evonik is an organofunctional silane oligomer. Acts as an adhesion promoter. It helps eliminate the need for special primers in numerous bonding applications. Exhibits excellent wetting on substrates and forms weather- and moisture-resistant bonds to substrates which are partially difficult to adhere, well balanced mechanical properties and significant VOC-reduction compared to conventional amino silanes. It leads to adequate adhesive cure and imparts additional flexibility and hydrophobicity.
